http://www.eerl.org/index.php?P=FullRecord&ResourceId=4819These case studies show how photovoltaic (PV) energy systems can be used today in a variety of ways to provide clean, reliable electricity. With continued research and development, the cost of PV-generated electricity should be even more competitive with conventional electric power in the next 5-10 years.Tue, 12 Apr 2011 04:11:19 -0400Region 8: Green Buildinghttp://www.eerl.org/index.php?P=FullRecord&ResourceId=7196

http://www.eerl.org/index.php?P=FullRecord&ResourceId=6525This is an online-interactive program that walks the user through the sizing of solar array strings. It has a data base of inverters and panels making it possible for the student to experiment with different sizes and configurations. It also integrates weather in the location (by zip code) allowing students to consider that variable. A useful tool for solar array installation. Limited to Sunyboy inverters and may be a little dated as none of the larger panels are represented. Provides nothing that a normal analysis of voltage High and Low limits of the inverter, divided by the voltage of the PV panels would give. Usable to people who don't understand the series type connections.Tue, 11 May 2010 03:06:32 -0400Effects of Tilt and Azimuth on Annual Incident Solar Radiation for United States Locationshttp://www.eerl.org/index.php?P=FullRecord&ResourceId=6524

http://www.eerl.org/index.php?P=FullRecord&ResourceId=6522Explanations for the critical areas of system design. These are specific for Canada, so the instructor is going to have to explain the differences for whatever latitude the class is at. However, it has some good simple instructions that the instructor could take and modify for his or her class. Best used as a supplement.Tue, 11 May 2010 02:21:08 -0400Prince Charles Hospital Solar Energy Feasibility Studyhttp://www.eerl.org/index.php?P=FullRecord&ResourceId=6521
http://www.eerl.org/index.php?P=FullRecord&ResourceId=6521This report was prepared for the Prince Charles Hospital in Australia. The whole report is a site appraisal assessment for outfitting the hospital with solar water heating. Within the appraisal, it is estimated that a well designed solar thermal system can contribute up to 70 percent of the annual energy needs required for the production of domestic hot water. They have suggestions for collector positioning and orientation for best results, along with roofing measurements. It also provides system sizing information for Prince Charles Hospital and benefit analysis and recommendations for which system would be best suited for the Hospital. This Australian 12-page report on the feasibility of large 8 m2 solar hot water panels found that they are not economically feasible due to low electricity rates.Tue, 11 May 2010 02:09:51 -0400Energy Policy Acthttp://www.eerl.org/index.php?P=FullRecord&ResourceId=6433
http://www.eerl.org/index.php?P=FullRecord&ResourceId=6433 Library Holdings.The Energy Policy Act (EPA) addresses energy production in the United States, including: (1) energy efficiency; (2) renewable energy; (3) oil and gas; (4) coal; (5) Tribal energy; (6) nuclear matters and security; (7) vehicles and motor fuels, including ethanol; (8) hydrogen; (9) electricity; (10) energy tax incentives; (11) hydropower and geothermal energy; and (12) climate change technology. For example, the Act provides loan guarantees for entities that develop or use innovative technologies that avoid the by-production of greenhouse gases. Another provision of the Act increases the amount of biofuel that must be mixed with gasoline sold in the United States.Wed, 28 Apr 2010 06:33:35 -0400Solar Geyser: Frequently Asked Questionshttp://www.eerl.org/index.php?P=FullRecord&ResourceId=6349

http://www.eerl.org/index.php?P=FullRecord&ResourceId=6278Solar thermal collectors or solar hot water heaters use the sun to heat either air, water, or a heat-transfer fluid in collectors that then heats a tank of water.Sun, 14 Mar 2010 07:06:11 -0400Flywheel Batteries: A New Spin on Energy Storagehttp://www.eerl.org/index.php?P=FullRecord&ResourceId=6137
http://www.eerl.org/index.php?P=FullRecord&ResourceId=6137A friend of mine recently installed solar panels on his roof to generate electricity. They were quite expensive, but my friend considers it an investment that will pay for itself in lower electricity bills over a period of decades. Of course, the panels generate electricity only when the sun is shining. The house is still connected to the electrical grid just like every other house in the neighborhood, but in such a way that it uses electricity from the grid only when the demand is greater than the output from the solar panels. When the panels are producing more electricity than is being used, the electric meter spins backward, and the electric company effectively buys the excess power. So if there were a power outage, the house would have electricity only during the day.Wed, 17 Feb 2010 04:33:15 -0500How do Photovoltaics Work?http://www.eerl.org/index.php?P=FullRecord&ResourceId=4829
http://www.eerl.org/index.php?P=FullRecord&ResourceId=4829Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.Sat, 2 May 2009 06:26:39 -0400U.S. DOE Solar Program's Thin-Film Partnershiphttp://www.eerl.org/index.php?P=FullRecord&ResourceId=4828

http://www.eerl.org/index.php?P=FullRecord&ResourceId=4827The U.S. Department of Energy's (DOE) PV Manufacturing Research and Development Project is managed by the National Renewable Energy Laboratory with support from Sandia National Laboratories. The Project team has worked for more than a decade in partnership with the U.S. PV industry to reduce manufacturing costs while significantly scaling up production capacity. Over this period, the PV Manufacturing R&D Project has issued several solicitations for partnerships that have resulted in more than 50 cost-shared R&D subcontracts addressing the cost and capacity goals of the Project.Sat, 2 May 2009 05:57:05 -0400Cadmium Use in Photovoltaicshttp://www.eerl.org/index.php?P=FullRecord&ResourceId=4826
